“…This can be achieved by increasing habitat complexity/diversity to provide refuges and alternative hosts and food resources to predators and parasitoids (Costello and Daane 2003;Duso et al 2004;Ponti et al 2005;Zanolli and Pavan 2011;Pozzebon et al 2015a;Wilson et al 2015) and reducing the use of non-selective pesticides (e.g., Jepsen et al 2007, Pozzebon et al 2015b. Biological control strategies against sucking pests can also be enhanced by inoculative or augmentative releases of natural enemies (Duso et al 1985;Daane et al 1996;Duso and Vettorazzo 1999;Daane et al 2008). Irrigation, fertilization, and cultivar choice can be also managed to reduce pest incidence and economic damage (Daane and Williams 2003;Costello 2008;Fornasiero et al 2012Fornasiero et al , 2016Cocco et al 2015).…”

Over-reliance on pesticides for pest control is inflicting serious damage to the environmental services that underpin agricultural productivity. The widespread use of systemic insecticides, neonicotinoids, and the phenylpyrazole fipronil in particular is assessed here in terms of their actual use in pest management, effects on crop yields, and the development of pest resistance to these compounds in many crops after two decades of usage. Resistance can only be overcome in the longterm by implementing methods that are not exclusively based on synthetic pesticides. A diverse range of pest management tactics is already available, all of which can achieve efficient pest control below the economic injury level while maintaining the productivity of the crops. A novel insurance method against crop failure is shown here as an example of alternative methods that can protect farmer's crops and their livelihoods without having to use insecticides. Finally, some concluding remarks about the need for a new framework for a truly sustainable agriculture that relies mainly on natural ecosystem services instead of chemicals are included; this reinforcing the previous WIA conclusions (van der Sluijs et al. Environ Sci Pollut Res 22:148-154, 2015).

“…It is recommended for use against grape thrips (Sunitha et al , 2008). Besides thrips it is also used as soil drench for control of mealybug, which is a severe vineyard pest of peninsular India as well as other grape growing nations (Fu‐Castillo et al , 2004; Daane et al , 2008). In a study by Frank & Nick (2006) on uptake and persistence of imidacloprid in grapevines it was found out that in younger vines uptake of imidacloprid was most rapid at the highest rates of application (281 and 562 g ha −1 ), reaching target threshold levels within the xylem fluid of 10 μg L 1 in 2 days while in older vines it was 6–8 days.…”

Introduction Grape, an important fruit crop of India, is affected by thrips that is a destructive sucking insect of grapevine. Imidacloprid, a neonicotinoid insecticide, gives very good control of this insect. Objectives Study of the residue persistence of imidacloprid on grapes, to estimate its residue deposit, half‐life of degradation, safe pre‐harvest interval and harvest time residues for consumption of this fruit after its multiple applications. Methods Extraction with acetonitrile, partitioning into dichloromethane, clean up with neutral alumina and estimation of residues with high‐pressure liquid chromatography, using a UV‐VIS detector at wavelength of 270 nm. Results Initial residue deposit of imidacloprid on grape berries following treatment of Confidor 200 SL at the recommended and double the recommended dose of 80 and 160 g a.i. ha−1 were 0.74 and 1.26 mg kg−1, respectively. Residues remained in the fruits up to 60 days but at a low level of 0.056 and 0.108 mg kg−1. The residues dissipated with the half‐life of 16.6 days from both the treatments. Conclusion The pre‐harvest interval recommended for safe consumption of grape berries is 60 days. Residues of imidacloprid in grape berries and soil at harvest (105 days after the last treatment) were observed to be below detectable limit of 0.05 mg kg−1 from both the treatments.

“…It is also possible that the observed activity on adult potato leafhopper reflects lower sensitivity of this insect species to imidacloprid than to other neonicotinoids. Imidacloprid has been used in vineyards for control of other sucking pests, including sharpshooters 10 and mealybugs,22 indicating that it is an effective insecticide for vine protection against other homoptera. In spite of the slower activity in imidacloprid treatments, it should be noted that, by 2 weeks after treatment, there were similarly high levels of control of potato leafhopper in all three insecticide treatments.…”
